Name the plant which performs photosynthesis even after closing of stomata?
1 Sunflower
2 Sugarcane
3 Pea
4 Papaya
Explanation:
Photosynthesis after closing of stomata can be performed by \({C_4}\) plants due to the presence of strong \(C{O_2}\) fixing enzyme PEPcase. Examples of \({C_4}\) plants are - Sugarcane, Maize, Sorghum, Amaranthus.

PEPcase has an advantage over RuBisCO. The advantage is
1 RuBisCO combines with \(C{O_2}\), but PEPcase does not
2 RuBisCO combines with \({O_2}\), but PEPcase does not
3 PEPcase is present in both mesophyll cells and bundle sheath cells, but RuBisCO does not
4 None of these
Explanation:
PEPcase (PEP carboxylase) is strictly a carboxylase whereas RuBisCO (RuBP carboxylase oxygenase) has active sites for both \({O_2}\) and \(C{O_2}\).

In \(\mathrm{C}_{4}\) plants, the process by which \(\mathrm{C}_{4}\) acid is converted into \(\mathrm{C}_{3}\) acid in the bundle sheath cell is known as
1 Carboxylation
2 Regeneration
3 Reduction
4 Decarboxylation
Explanation:
In \(\mathrm{C}_{4}\) plants, the process by which \(\mathrm{C}_{4}\) acids are converted into \(\mathrm{C} 3\) acids in the bundle sheath cell is known as decarboxylation. Shortly after the discovery of \(\mathrm{C}_{4}\) cycle the crassulacean acid metabolism (CAM) pathway was dissected and elucidated as a \(\mathrm{C}_{4}\) variant. This pathway is found in desert succulents and epiphytes. In the typical \(\mathrm{C}_{4}\) cycle, the fixation reaction occurred in a mesophyll cell and the decarboxylation reaction occurred in a bundle sheath cell, Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide \(\left(\mathrm{CO}_{2}\right)\). Enzymes that catalyze decarboxylation are called decarboxylases.
